About this task
CAUTION:
If BitLocker is not suspended before updating the BIOS, the next time you reboot the computer it
will not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress, and the
computer will ask for this on each reboot. If the recovery key is not known this can result in data loss or an
unnecessary operating system reinstall. For more information about this subject, search in the Knowledge Base
Resource at www.dell.com/support.
